            transaction; or

                  (v) If during any period of two consecutive years, individuals

      or report or item therein) under the Exchange Act, disclosing beneficial
      ownership by it of shares of Voting Stock, whether in excess of 20 percent
      or otherwise, or because the Company reports that a change in control of
      the Company has or may have occurred or will or may occur in the future by
      reason of such beneficial ownership.

      Section 2. Vesting. Effective February 24, 2003, a Participant who is the

the Lubrizol Pension Plan.

      Section 4. Early Retirement Eligibility and Determination of Benefit.
Effective February 26, 2001, each Participant who retires from employment with
the Company at or after age 55, but prior to his Normal Retirement Date, shall

the Lubrizol Pension Plan.

      Section 5. Termination of Employment. Effective February 26, 2001, if a
Participant terminates employment prior to age 55, he shall receive the
actuarial equivalent of his vested supplemental retirement benefit determined
under Section 3 in a single lump-sum payment; such actuarial equivalent of which

the Lubrizol Pension Plan as in effect on the date the Participant terminates
employment in accordance with this Section 5.

      Section 6. Payment to Participant. (Effective November 27, 1995)

            (a) Each Participant who retires in accordance with Sections 3 or 4
      shall receive payment of his supplemental pension benefit under the Plan
      determined as of his date of retirement in the standard form of benefit of
      a monthly retirement benefit commencing within 30 days following
      retirement and payable to such Participant for his lifetime following such
      retirement, with the continuance to his Beneficiary of such amount after
      his death for the remainder, if any, of the 120-month term that commenced
      with the date as of which the first payment of such monthly benefit is
      made, and with any such monthly benefits remaining unpaid upon the death
      of the survivor of the Participant and his Beneficiary to be made to the
      estate of such survivor.

            (b) Participants may instead elect within a 60 day period commencing
      90 days prior to retirement to receive the actuarial equivalent of the
      standard form of benefit determined under paragraph a, on the date of
      retirement, in accordance with any one of the following options:

<PAGE>

                  (i) a single lump-sum payment payable within 30 days following
            retirement;

                  (ii) effective October 1, 2000, a single lump-sum payment
            payable within 30 days following the end of the calendar year in
            which the Participant retires. Interest on the lump-sum deferral
            shall accrue and be paid with the lump-sum; such interest to be
            computed at the applicable interest rate, as defined in Section
            417(e)(3)(A)(ii)(II) of the Code, in effect on the date of
            retirement;

                  (iii) a reduced monthly retirement benefit commencing within
            30 days following retirement and payable to such Participant for his
            lifetime following his retirement, with the continuance of a monthly
            benefit equal to fifty percent (50%) of such reduced amount after
            his death to his Beneficiary during the lifetime of the Beneficiary,
            provided that such Beneficiary is living at the time of such
            Participant's retirement and survives him;

                  (iv) a reduced monthly retirement benefit commencing within 30
            days following retirement and payable to such Participant for his
            lifetime following his retirement, with the continuance of a monthly
            benefit equal to one hundred percent (100%) of such reduced amount
            after his death to his Beneficiary during the lifetime of the
            Beneficiary, provided such Beneficiary is living at the time of such
            Participant's retirement and survives him.

                  (v) annual installments of up to ten payments, the first of
            which shall be paid within 30 days following retirement, and
            subsequent installments of which shall be paid on the anniversary
            date of the payment of the first installment. Such installments
            shall be determined by dividing the commuted lump-sum equivalent of
            the supplemental retirement benefit (determined in the same manner
            as under the Lubrizol Pension Plan) by the number of installments to
            be paid and adjusting for interest based on the interest rate used
            to determine the commuted lump-sum payment. Installments after the
            first installment shall include such interest which accrues during
            the 12-month period occurring since the date the prior installment
            was paid.

      Notwithstanding the foregoing provisions of the Plan to the contrary, if
the present actuarial value of any retirement benefit or survivor benefit under
the Plan to any person, determined as described above, is less than $25,000,
such benefit shall be paid in a single lump-sum payment to such person within 30
days following retirement.

      Section 7. Payment in the Event of Death Prior to Commencement of
Distribution. Effective February 26, 2001, if a Participant dies prior to
commencement of benefits under the Plan, his surviving spouse, if any, shall be
eligible for a survivor benefit which is equal to one-half of the reduced
monthly benefit the Participant would have received under the Plan if the
Participant was 100 percent vested in his accrued supplemental retirement
benefit, had terminated employment on the day before his death and had elected
to receive his benefit hereunder in the form of a 50 percent joint and survivor
annuity. In

<PAGE>

making the determinations and reductions required in this Section 7, the Company
shall apply the assumptions then in use under the Lubrizol Pension Plan. For
purposes hereof, a surviving spouse shall only be eligible for a benefit under
this Section 7, if such spouse had been married to the deceased Participant for
at least one year as of the date of the Participant's death.

      Section 8. Actuarial Factors. All actuarial assumptions and factors used
in this Plan shall be the same as those used in the Lubrizol Pension Plan.

      Section 9. Funding. The obligation of the Company to pay benefits provided
hereunder shall be unfunded and unsecured and such benefits shall be paid by the
Company out of its general funds. In order to provide a source of payment for
its obligations under the Plan, the Company may cause a trust fund to be
maintained and/or arrange for insurance contracts. Subject to the provisions of
the trust agreement governing any such trust fund or the insurance contract, the
obligation of the Company under the Plan to provide a Participant with a benefit
shall nonetheless constitute the unsecured promise of the Company to make
payments as provided herein, and no person shall have any interest in, or a lien
or prior claim upon, any property of the Company.

      Section 10. Plan Administrator. The Company shall be the plan
administrator of the Plan. The plan administrator shall perform all ministerial
functions with respect to the Plan. Further, the plan administrator shall have
full power and authority to interpret and construe the Plan and shall determine
all questions arising in the administration, interpretation, and application of
the Plan. Any such determination shall be conclusive and binding on all persons.
The plan administrator shall employ such advisors or agents as it may deem
necessary or advisable to assist it in carrying out its duties hereunder.

      Section 11. Not a Contract of Continuing Employment. Nothing herein
contained shall be construed as a commitment or agreement on the part of the
Participant to continue his employment with the Company, and nothing herein
contained shall be construed as a commitment or agreement on the part of the
Company to continue the employment or the annual rate of compensation of the
Participant for any period, and the Participant shall remain subject to
discharge to the same extent as if this Plan had never been put into effect.

      Section 12. Right of Amendment and Termination. Effective October 1, 1994,
the Company reserves the right to amend or terminate the Plan in whole or in
part at any time and to suspend operation of the Plan, in whole or in part, at
any time, by resolution or written action of its Board of Directors or by action
of a committee to which such authority has been delegated by the Board of
Directors; provided, however, that no amendment shall result in the forfeiture
or reduction of the interest of any Participant or person claiming under or
through any one or more of them pursuant to the Plan. Any amendment of the Plan
shall be in writing and signed by authorized individuals.

      Section 13. Termination and Distribution of Accrued Benefits.

            (a) The Plan may be terminated at any time by the Company, and in
      that event the amount of the accrued benefits as of the date of such
      termination shall remain an obligation of the Company and shall be payable
      as if the Plan had not been terminated.

<PAGE>

            (b) Effective December 31, 2004, this Plan is terminated with
      respect to further accruals of benefits. Benefits which have accrued
      hereunder as of December 31, 2004 shall continue to be administered under
      the terms and provisions of this Plan.

      Section 14. Construction. Where necessary or appropriate to the meaning
hereof, the singular shall be deemed to include the plural, the plural to
include the singular, the masculine to include the feminine, and the feminine to
include the masculine.

      Section 15. Severability. In the event any provision of the Plan is deemed
invalid, such provision shall be deemed to be severed from the Plan, and the
remainder of the Plan shall continue to be in full force and effect.

      Section 16. Governing Law. Except as otherwise provided, the provisions of
the Plan shall be construed and enforced in accordance with the laws of the
State of Ohio.
